2009-06-09ARM: OMAP4: SMP: Add mpu timer support for OMAP4430Santosh Shilimkar2-0/+30
This patch adds SMP platform specific parts for local(mpu) timer support for OMAP4430 platform. Each Cortex-a9 core has it's own local timer in the MPU domain. These timers are not in wakeup domain. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>
2009-06-09ARM: OMAP4: SMP: Add OMAP4430 SMP board filesSantosh Shilimkar1-0/+51
This patch adds SMP platform files support for OMAP4430SDP. TI's OMAP4430 SOC is based on ARM Cortex-A9 SMP architecture. It's a dual core SOC with GIC used for interrupt handling and SCU for cache coherency. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>

2009-05-29ARM: OMAP2/3: Add generic smc91x support when connected to GPMCTony Lindgren1-0/+42
Convert the board-rx51 smc91x code to be generic and make the boards to use it. This allows future recalculation of the timings when the source clock gets scaled. Also correct the rx51 interrupt to be IORESOURCE_IRQ_HIGHLEVEL. Thanks to Paul Walmsley <paul@pwsan.com> for better GPMC timing calculations. Signed-off-by: Tony Lindgren <tony@atomide.com>
2009-05-29ARM: OMAP2/3: Add generic onenand support when connected to GPMCJuha Yrjola1-2/+20
Add generic onenand support when connected to GPMC and make the boards to use it. The patch has been modified to make it more generic to support all the boards with GPMC. The patch also remove unused prototype for omap2_onenand_rephase(void). Note that board-apollon.c is currently using the MTD_ONENAND_GENERIC and setting the GPMC timings in the bootloader. Setting the GPMC timings in the bootloader will not allow supporting frequency scaling for the onenand source clock. Signed-off-by: Tony Lindgren <tony@atomide.com>

2009-05-28OMAP3: PM: Add D2D clocks and auto-idle setup to PRCM initKevin Hilman1-0/+4

Also add omap3_d2d_idle() function called durint PRCM setup which ensures D2D pins are MUX'd correctly to enable retention for standalone (no-modem) devices.

2009-05-28OMAP3: PM: UART: disable clocks when idle and off-mode supportKevin Hilman2-2/+9
This patch allows the UART clocks to be disabled when the OMAP UARTs are inactive, thus permitting the chip to hit retention in idle. After the expiration of an activity timer, each UART is allowed to disable its clocks so the system can enter retention. The activity timer is (re)activated on any UART interrupt, UART wake event or any IO pad wakeup. The actual disable of the UART clocks is done in the 'prepare_idle' hook called from the OMAP idle loop. While the activity timer is active, the smart-idle mode of the UART is also disabled. This is due to a "feature" of the UART module that after a UART wakeup, the smart-idle mode may be entered before the UART has communicated the interrupt, or upon TX, an idle mode may be entered before the TX FIFOs are emptied. Upon suspend, the 'prepare_suspend' hook cancels any pending activity timers and allows the clocks to be disabled immediately. In addition, upon disabling clocks the UART state is saved in case of an off-mode transition while clocks are off. Special thanks to Tero Kristo for the initial ideas and first versions of UART idle support, and to Jouni Hogander for extra testing and bugfixes.

This patch is to sync the core linux-omap PM code with mainline. This code has evolved and been used for a while the linux-omap tree, but the attempt here is to finally get this into mainline. Following this will be a series of patches from the 'PM branch' of the linux-omap tree to add full PM hardware support from the linux-omap tree.

2009-05-13OMAP3 clock: only unlock SDRC DLL if SDRC clk < 83MHzPaul Walmsley1-2/+4
According to the 34xx TRM Rev. K section 11.2.4.4.11.1 "Purpose of the DLL/CDL Module," the SDRC delay-locked-loop can be locked at any SDRC clock frequency from 83MHz to 166MHz. CDP code unconditionally unlocked the DLL whenever shifting to a lower SDRC speed, but this seems unnecessary and error-prone, as the DLL is no longer able to compensate for process, voltage, and temperature variations. Instead, only unlock the DLL when the SDRC clock rate would be less than 83MHz. Signed-off-by: Paul Walmsley <paul@pwsan.com>

2009-04-24OMAP2/3 GPTIMER: allow system tick GPTIMER to be changed in board-*.c filesPaul Walmsley2-1/+18
Add a function omap2_gp_clockevent_set_gptimer() for board-*.c files to use in .init_irq functions to configure the system tick GPTIMER. Practical choices at this point are GPTIMER1 or GPTIMER12. Both of these timers are in the WKUP powerdomain, and so are unaffected by chip power management. GPTIMER1 can use sys_clk as a source, for applications where a high-resolution timer is more important than power management. GPTIMER12 has the special property that it has the secure 32kHz oscillator as its source clock, which may be less prone to glitches than the off-chip 32kHz oscillator. But on HS devices, it may not be available for Linux use. It appears that most boards are fine with GPTIMER1, but BeagleBoard should use GPTIMER12 when using a 32KiHz timer source, due to hardware bugs in revisions B4 and below. Modify board-omap3beagle.c to use GPTIMER12. This patch originally used a Kbuild config option to select the GPTIMER, but was changed to allow this to be specified in board-*.c files, per Tony's request. Kalle Vallo <kalle.valo@nokia.com> found a bug in an earlier version of this patch - thanks Kalle. Tested on Beagle rev B4 ES2.1, with and without CONFIG_OMAP_32K_TIMER, and 3430SDP.
